SPECIFICATION forming part of Letters Patent No. 722,101, dated March 3, 1903.

Application filed September 27,1902. berial No. 125,041. (No model.)

To all whom it nuty concern:

Be it known that I, CLAY TON HARRIS, a resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Sheet-Metal Window-Frames; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the construction of metal window frames and sashes, and has for its object to produce a fireproof frame and sash of sheet metal whose simple form of construction materially reduces the cost of production and at the same time is practical and easy to operate. It is fully explained in this specification and illus trated in the accompanying drawings.

Figure 1 represents the frame and sash as set in the brickwork of a building. Fig. 2 represents an enlarged longitudinal section on line 2 2 of Fig. 1, showing the head and sill with the sash and windows in place. Fig. 3 is the lower portion of the same section as Fig. 2, showing the casing with the windowsash removed and the locked cover over the weight-pocket. Fig. 4: represents a transverse section of the window-jamb on line 4 4, Fig. 3. Fig. 5 represents an enlarged perspective View of the cover for the weightpocket. Fig. 6 shows an enlarged longitudinal section of the cover on line 6 6, Fig. 5, illustrating the construction of the lock. Fig. 7 shows the end of one of the muntin-strips employed to secure the glass in the sash. Fig. 8 illustrates a section of the glass and the position of the muntin-strips, which secure it in place.

In the construction, A is the jamb, (see Fig. 4,) which is constructed with a separate or removable back a to facilitate assembling. This may be clamped, riveted, or otherwise secured in place after the thick metal strips b and C have been riveted or otherwise secured in place on the inner side.

B is the parting-strip, which sets in a longitudinal groove made in the jamb to receive it, and is held in place by bolts 0 c, which pass through it and are threaded into a thick strip of iron I), fixed to the inner side of the jamb and tapped to receive said bolts. 0 is another strip of iron, also tapped out and fixed to the inner side of the jamb to receive the screws d d, which hold the outer strip D in place. These strips run the entire length of the jamb, so they may be drilled and tapped at any convenient place. Riveting is found to be the most practical way of securing them in position. The head E is bentup in one piece, with its edges locked together at e. The hollow sill F is also made in one piece and locked at f. This sill may be filled with cement, wood, or other suitable material.

At the lower end of the jamb and in the groove where the lower-sash runs is a weightpocket, through which window-weights may be inserted and removed. This pocket is covered by the metal cover G, which looks in place by the form of lock illustrated at g in Fig. (I The side edges of this cover are hidden by the strips B and D, making it very secure and presenting a neat appearance.

H and J (see Fig. 8) are the muntins or strips employed to secure the outer edges of the glass R in place. Fig. 7 represents the end of muntin II cut away to fit the grooves which receive the upper and lower edges of the glass. This figure also shows the rib or fin i cut away at h to allow the screws to pass through. Into this muntin H is placed and fastened by rivets a strip of iron tapped at intervals to receive the screws 70. (See Fig. 8.) The muntin J is placed on the opposite, side of the glass and receives the heads of the bolts. At m is a lip projecting from each end of the ribbed muntin-strip to enter the side frames for the purpose of holding or binding said muntin in place. These strips constructed as shown and described present a smooth and handsome finish to the Windowframe and are easily removable to allow the resetting of broken glass without disturbing the outer frames.

This improved construction while simple and durable is found to be secure and to work well in practice.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a sheet-metal window-sash, a hollow muntin-strip, a reinforcing-piece on the inner side of said strip, a fin or rib projecting from said strip for the purpose of centering it between the edges of the window-pane, in combination with a muntin-strip placed on the opposite side of the window-pane to receive the ends of fasteners and serve as a binder to secure the edges of said window-pane substantially as described.

2. In a sheet-metal window-frame, the combination of a head made in one piece, the jamb made with a separate back, a groove in the face of said jamb -to receive the partingstrips, reinforcing-strips on the inner side of said jamb into which the bolts are screwed which fasten the strips, a weight-pocket, in said jamb, a removable cover to said weightpocket, means for locking said cover in place, substantially as described.

3. In a sheet-metal window-frame, in combination the head made in one piece, the sill made in one piece, the jarnbs having removable backs, hollow parting-strips, bolts for securing said strips in place, reinforcing or backing strips fixed on the inner side of said jambs tapped to receive the threaded portion of said bolts, substantially as described.

4. In a sheet-metal window-sash, hollow m'untin-strips placed on each side of the pane for holding the edges of the glass in place, bolts to bind said strips to the glass, a centering rib or fin on one of said muntin-strips cut away at intervals to allow the bolts to pass through, a reinforcing or backing strip on the inner side of said ribbed strip tapped to receive the threaded portion of said bolt, substan tially as described.

5. In a sheet-metal window-sash, a hollow inuntin-strip, a reinforcing-piece on the inner side of said strip, a fin or rib projecting from said strip for the purpose of centering it between the edges of the window-pane, in combination with a muntin-strip placed on the opposite side of the window-pane to receive the heads of the screws and serve as a binder to secure the edges of said windowpanes, lips on the ends of said ribbed rnnntin to enter the side frames for the purpose of assisting in holding or binding the ends of said muntin in place, substantially as described.

In testimony whereof I have hereunto set my hand this 19th day of September, A. D. 1902.

CLAYTON HARRIS.
